Introduction:
The portable repeater is developed with the latest technologies of COFDM modulation and MPEG-2 video compression. This equipment can realize wireless transmission with high definition video and stereo audio. Especially, in the urban and mountainous environments, the portable repeater is the ideal solution for the NLOS (non line-of-sight) transmission. Since its powerful function and it is easy to be carried and installed everywhere, the repeater has many application fields such as: Broadcasting, Military, Public Security, Forest Fire Prevention, Firefighting, Oil and Gas Industries, Traffic Police, Disaster Management, Railway.
Main Features:
Inset high-performace amplifier
Lithium battery for power supply
Convenient to be carried and installed
COFDM modulation and MPEG-2 video compression
Great security by encryption of AES 128 bit/ALLTECH Basic Scrambling
Good transmission with high definition image and stereo audio
Adjustable working frequency, LCD board displays the working frequency
Firm aluminium enclosure with built-in cooling fans, waterproof and shockproof
Stable transmission in NLOS(non line-of-sight)and high speed mobile condition.
Transmission range can be up to 100km in LOS(line-of-sight)environment
Product Application:
For the wireless transmission system, if there are high buildings and mountains between the first responder and the receiving center, the transmission quality is easy to be disturbed. We can use the portable repeater to relay the camera's output signals from the first responder to the commanding center.
